Adjustable Trim and Directional Reverse Bucket Install

[SamCF]

I'm wondering if you could do the trim mod without the reverse gate mod. Could you get the correct nozzle (for the 90 degree change in pivot bolts) and then use your same boat deflector on the trim ring? That would be something I'd be interested in trying. You wouldn't get as much up trim that way probably because of the reverse thrust port would get in the way but down trim is more interesting to me anyway. I know others are really excited about the ski reverse gate style but for me I really like the way the boat reverse gates turn intuitively like a prop boat.

The boat steering nozzle will not fit over the trim ring. The trim ring mounts to the jet nozzle and the steering nozzle mounts over the top of the trim ring.

As mentioned previously. It would be amazing if someone could make this into a complete kit, or at least provide the parts which need to be modified or custom made. I'm sure many people would be all over it.

Ah, yeah I guess that makes sense.

Thanks @SamCF , added to the FAQ under steering and trim tabs headings,

Great work @SamCF

Nice job @SamCF ! I want a ride!

 

[JBehrens]

Nice job! One of the coolest mods I have seen for the 19ft's, makes me want one now...

I wondering how this would work with a 195 having the articulating keel. Would where the AK connects to the pump interfere with the trim adjustment/location of where the AK connects to the pump?

The trim would be complicated for sure. You would need to make a custom bracket to connect the keel and steering nozzle. Like a Y shaped bracket that mounted to the keel with Delrin bushing around the nozzle that allowed the trim to slide up and down. Might not be worth the trouble.

This got me thinking about what it would take to just do the reverse bucket. You would only need the 2 mounting brackets, the bucket and bolts and spacers. Drill and tap your jet pump venturi. Then move the shift linkage to the side. Maybe $220 per jet.

I think the lateral thruster from JBP would do the same thing for about the same money though.

What did you end up using for controls in the boat? Awesome mod and has me interested in for next winters list! Great job!

Yea I can see this being a bit more involved with the articulating rudder on my 192. I'd love to have that bucket though and it's how these boats should come from the freaking factory.

Is see that in reverse turning is improved but what about straight reverse thust. I would think it hits the stern, especially on a twin that the inbord exit would be directed into the center of the transom.
I personally wouldnt like the reverse steering to be oposite from what is factory, i would deffinitly get used to it but when you give the controls to someone else there is the possiility to have problems.

Dont get me wrong this is still a great mod.

The thrust goes beside the boat instead of under. I like that more because I can back into shallow water without stirring up sand and rocks.

It has much better reverse speed than stock. As far as direction, the boat spins in the direction you turn the wheel.

100% agree.
This is totally doable in the twins as well.

Not even close, I would think. Plus, the issue with LTEs will be clogging - those are basically funnels... I often have some debris/grit coming through the pumps, where I boat it is inevitable (same with weeds, I don't have that here).
(totally not trying to say anything negative about on JBP LTE's! Albeit I guess I just did... But what can you do... I'm just voicing my opinion on something I care about; The LTEs are a big step forward)

I like the idea of the JBP LTE but the level of control that you can get from the ski bucket is impressive, just requires more work.

Now if the trim could be made to work with the AK that would be the holy grail for the 19ft's. Those with the AK could probably have section of the top cut away to give clearance for the trim, the hard part would be connecting it to the pump.

Damn! You beat me to this mod! hahaha.
Sorry I've been awol guys, I miss you all! lol. I've been so busy with my motorhome rebuild I've been neglecting my poor boat.

So the big question I had when I was thinking about doing this mod is what effect does it have on speed? I know it would be nice to change/lower the jet spray when tubing or stuff like that, but I really wanted to know if it made a difference in top speed. If it did, you could also simply machine the outlets to have more angle up or down if somebody wanted a cheap and easy mod. Certainly not as nice as having total control, but much easier and cheaper.

Thanks for posting all the part numbers needed too, that was awesome! I had started doing the same research on which waverunner hardware to use, I just never got around to going forward with it myself.

Another question is do you notice a difference/problem with "neutral" as far as where the nozzle angle is at? In other words, do you have to remember to have the trim angle at a certain spot so the boat will stay in one place when the handles are in the neutral position? Seems like it could be an issue since the bucket to nozzle relationship changes as the trim angle changes.

Good job though!

I saw a 2.4 mph increase, but there are a lot of different factors at work. It for sure won't slow you down.

I didn't try for top speed with the trim down, but we did go mid 40's. The bow is firmly planted and the steering is more sensitive.

Neutral is perfect until you fully lower the trim. Then it creeps forward slowly.

You have complete, total, precise control in Neutral and Reverse. Response to steering input is instant.

At slow speeds you can drop into neutral and spin the boat. Approaching a dock you can nose in at a comfortable speed then drop to neutral or reverse and rotate into position.

 

[haknslash]

Yes I would expect a decrease in speed with the nozzle trimmed down since more of the bow surface is in the water. It would be like when I have people sit in the bow at speed. Handling gets better as does slicing through a wave since more of the V is in the water as opposed to the mid and rear sections of the hull where it begins to get flatter. The sacrifice is top speed but depending on conditions this may be desired tradeoff and that's where the beauty of an adjustable trim nozzle shines. I like this approach better than trim tabs! My XP had it and it was great for dialing in just how I wanted the ski to perform given the water conditions or style of riding I wanted to do.

What would be really interesting for surfing is adjustable trim tabs (for listing) + adjustable nozzle (to divert jet thrust down).

 

[Jgorm]

Awesome work

 

[Julian]

How far does the nozzle trim up? Can you create a cool looking rooster tail???? That would be fun
